One morning, I woke up to an odd sound. Crunch. Crunch. I walked into the kitchen to find Snickers—my curious tabby—elbow-deep in our dog’s food bowl, chomping away like it was gourmet. I froze. “Can my cat eat dog food?” I wondered, half-panicked, half-impressed by her boldness.

Turns out, I’m not the only one asking that question.
Whether your cat sneakily raids the dog’s dinner or you’re simply out of kibble and wondering if a quick swap is okay, you’re in the right place. Let’s unravel the furry truth together.
Is It Safe? Can Cats Eat Dog Food Safely?
Here’s the thing about cats and dog food: they can eat it, but that doesn’t mean they should.
A nibble here and there? Probably fine. But regular meals? That’s where trouble can start.
Cats are obligate carnivores—they’re wired to eat a meat-heavy diet. Dog food is made for omnivores and lacks some of the core nutrients cats need.
Here’s what’s missing in most dog food:
- Taurine – vital for heart and eye health
- Arachidonic acid – a fatty acid cats can’t make themselves
- Vitamin A – dogs can convert it from plant sources; cats cannot
- High protein content – cats require more than most dogs do
So while your cat won’t get sick from a single bite, a regular diet of dog food could lead to long-term problems like poor vision, heart issues, or a dull coat.
What If My Cat Only Ate a Little?
If your cat snuck a few bites, don’t worry too much.
Snickers has done it before too—usually when I forget to refill her bowl on time. Most vets agree that an occasional nibble is unlikely to cause harm.
But if your cat consistently eats your dog’s food, it’s time to intervene.
Can Cats Eat Wet Dog Food or Canned Dog Food?
This is a common question. People often ask, can cats eat wet dog food? Or, is canned dog food any better for them?
Not really.
Even canned dog food still lacks essential nutrients that cats need. The texture might make it seem more appealing, but it’s no more nutritionally complete for a cat than dry dog food.
Some canned varieties also contain additives or fillers that can irritate a cat’s stomach. And let’s be honest—most canned dog food smells like old stew. Your cat deserves better.
Can Cats Get Sick from Eating Dog Food?
Yes, especially if they eat it regularly.
If your cat eats too much dog food, you might notice:
- Upset stomach (vomiting or diarrhea)
- Low energy
- Dull coat
- Muscle loss or weight changes
If these symptoms appear, check in with your vet. Early intervention can prevent bigger issues later.
Why Do Cats Like Dog Food?
Good question—and one I’ve asked myself.
Dog food often has a strong smell, especially if it’s meat-heavy. That can lure curious cats like Snickers who are always sniffing around. And if your cat’s regular food is bland or repetitive, they might be looking for something new—even if it’s not good for them.
That doesn’t mean your cat prefers it nutritionally—it just means they’re being, well, a cat.
What to Do If You’re Out of Cat Food (And Only Have Dog Food)
We’ve all had that late-night panic: no cat food in the house, and your feline is not happy.
For a single meal, feeding a small portion of dog food won’t hurt. But don’t rely on it more than once.
Instead, try offering:
- Plain, unseasoned cooked chicken or turkey
- A scrambled egg (no butter or salt)
- A small amount of tuna in water (not oil or flavored)
These are far better emergency meals than dog food, and much closer to what your cat’s body actually needs.
What Should I Feed Instead? (Better Options for Curious Cats)
If your cat keeps sniffing around the dog bowl, it might be time to mix things up in their own dish. Sometimes they’re bored, sometimes they’re just being nosy—but either way, giving them something more exciting (and nutritionally complete) can help.
Here are a few options I always keep stocked at home—especially after Snickers’ dog food phase:
- Tiki Cat After Dark – It’s rich in animal protein and loaded with taurine, which cats absolutely need. Plus, the broth keeps them hydrated and interested.
- Hill’s Science Diet for Indoor Cats – This is one of those boring-but-reliable choices. Vets love it, and it covers all the essentials without fluff.
- Instinct Raw Boost Mixers – These little freeze-dried toppers are magic. I sprinkle them over kibble when Snickers gets picky, and suddenly she’s all in.
Buying through these links helps support the site (and keeps Snickers well-fed). No extra cost to you—promise.
If you rotate a few of these or keep them handy for backup, you’re way less likely to end up wondering can cats eat canned dog food at 9 p.m.
FAQs About Cats Eating Dog Food

Yes, in an emergency. Just return to cat food as soon as possible.
Why is my cat obsessed with dog food?
Probably the smell or taste. But it’s not a sign that it’s good for them.

Final Thoughts: Should Cats Eat Dog Food?
So, can cats eat dog food safely? Technically, yes—for a meal or two in a pinch. But it’s not built for feline nutrition, and over time, it can cause real health issues.
If you catch your cat stealing bites here and there, it’s not the end of the world. But if it’s becoming a habit, make changes now.
Cats are complicated, curious creatures. But when it comes to their food, simple is better: stick with meals made for them. They’ll be healthier, happier—and a lot less likely to sneak snacks from the dog.
Have you caught your cat doing this too? Let me know your story—Snickers and I would love to hear it.
